Can I use dconf-editor to modify Gconf settings?
Solution 1:
No. There is a transition going on here since gconf-editor (xml backend) is going to be phased out in favor of dconf-editor (gnome 3 binary blob). So, you can expect more and more settings in gconf to become invalid or removed and new settings to appear in dconf.
